Hi, I have this circuit diagram
http://www.edn.com/article/CA316054.html
This schematic shows 5V output "5v to circuit" do I need to connect it to multiple 5V "inputs" shown as empty circles shown as "5V"?
Also the LM324 is 14pin chip. What pins I need to connect to "+", "-", "R7"?
"1IN +" "pin3" connect to "+"
"1IN" "pin2" connect to "-"
"1out" "pin1" connect to "R7"
"GND" "pin11" connecto to ground.
What and where do I connect "TTL input"?

"1IN +" "pin3" connect to "+"
"1IN" "pin2" connect to "-"
"1out" "pin1" connect to "R7"
"GND" "pin11" connecto to ground.
